I have five pairs presently (four full-size models for at home, one ECH for on the go), six if you count a set that is no longer hooked up/functional (it's complicated). This has gone up and down over the last few years, the last time I had many models at home, I started selling them off - that likely won't happen now (I'm on the fence about buying "number five" at the moment).
I found this quote interesting, and thought I'd explain at least my perspective. I have all of my at-home headphones (the ECHs are basically never counted and I tend to forget them until I'm using them (which, ironically, is near daily); they live in my briefcase) on inexpensive stands (banana hooks) on a shelf. Sometimes I will deliberately select a given can if I'd like to listen to a specific album that I know it will excel at, but generally I pick a can based on the signature I'd like to hear, now how they interact with a specific genre (in other words, if I want a very spacious presentation, there's a can for that; if I want a very bassy presentation, there's a can for that). One more pragmatic feature of having this arrangement, is during cold or hot months, I can switch between cans if one is too cold (for example the leather pads being stiff) or if one warms up too much on my head (...also usually the leather pads).
The biggest complaints/problems faced with this arrangement are the overall weight on the shelf (it's a very shoddily built shelf, mind you), and cord management (I should say "that wire hell that I ignore"). Back in the day I had a desk with large drawers, and just kept all of the headphones in one drawer - it actually worked very nicely in terms of keeping the wire mess out of sight, but it was a pain if you wanted something "at the bottom."
Pretty much, the summary is: you do whatever the hell you want, it's excessive to the max, and as long as you get on well with all of the headphones you've selected, there's really no legitimate complaints. It *does* suck though when you've got one pair of cans that stands apart from the others, and you're constantly comparing things. I'm glad to be done with that phase.

To the people with multiple headphones: How does that work? Do you simply swap out headphones based on what your current musical muse is?
Legitimate question; I'm not sure how this is done.
